ANTENNAS

Portable Antennas
These FLEXTRON portable antennas are designed for specialized or standard cellular, PCS and ISM-band applications. The company has available 5/8-, 1/2- and 1/4-wave designs in rugged injection-molded, neoprene or the economical polyvinyl-chloride-coated shrink sleeve. Telescoping and articulating coil and whip designs are also available for device applications. All of the antennas are available with a variety of connectors and adapters, and can be optimized to a specific application.

PCS/DCS Dual Linear Patch Antenna
The model S1857HVP12NF PCS/digital communications system (DCS) dual linear patch antenna provides for reception and transmission of linearly polarized signals in the 1850 to 1990 and 1710 to 1880 MHz frequency bands. The antenna is composed of a broadband patch that provides a minimum of 7 dBi gain and features one feed for horizontal polarization and one feed for vertical polarization. The antenna’s SWR is 1.5 (max) on 50 W impedance. The housing is vacuumed formed out of polyvinyl chloride in a rugged, UV-stabilized radome that is weather resistant for use in outdoor applications. Size: 6" x 6" x 1".

Planar Antennas
The Discreet™ series antennas are designed for low profile installation and can be used for either in-building distributed antenna systems or in outdoor situations. The units are easy to install and include models in five frequency bands: the model ASPPD-2988 operates from 824 to 894 MHz (Advanced Mobile Phone Service (AMPS) cellular); the model ASPPG2988 operates from 880 to 960 MHz (GSM/spread spectrum); the model ASPPK2988 operates from 1710 to 1880 MHz (DCS1800); the model ASPPM2988 operates from 1850 to 1990 MHz (PCS applications); and the model ASPPT2988 operates from 2.3 to 2.5 GHz (spread spectrum). All models are supplied with an SMA female connector, meet RS-329 windload specifications and are designed for extreme weather conditions.
